DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the contents of a video recording apparatus having a UPS (Uninterruptible Power Supply) function according to the present invention will be described in detail with reference to the accompanying drawings.

The video recording apparatus according to the present invention includes three circuit modules. The circuit module includes a main module 1, a UPS extension module 2, and a front module Front Module (3).

1 is a block diagram of a main module of a video recording apparatus according to the present invention.

The main module 1 includes a main processor 10 for controlling video input and output, video data storage, and other functions of a video recording apparatus, and video and audio signals of a multi-channel camera 11 such as 4/8 channel A video decoder 12 for receiving and processing input video data, a video output unit 13 for outputting the input video data to the outside, a monitor output unit 14 for outputting video data to a monitor, A terminal block 16 for inputting or outputting various data and a network connection unit 15 for network connection with an IP camera and a client PC and a video output setting (17) and the like.

The main processor 10 is provided with a memory 18 for processing input and output data, a NAND flash 19 for storing processed data, a hard disk 20 for storing processed data, and the like And a storage means.

A dedicated network PHY chip for connection to the IP camera network and a dedicated network PHY chip for connection to the client computer are additionally provided between the network connection unit 15 and the main processor 10. [

The image input from the multi-channel camera 11 is capable of inputting camera image data of 4/8 channel analog HD transmission method from 4/8 BON (Bayonet Neill Concelman) port, and is connected to a network connection part 15 ) And a LAN (Local Area Network) port to receive video data of 2 channels (8 channels, DVR 4 channels).

The video data output is output to an HDMI (High-Definition Multimedia Interface), VGA (Video Graphics Array), HD (High Definition) Spot, SD (Standard Definition) The image output setting unit 17 is used for the image output of various resolutions and the 4K resolution (4K Ultra High Definition) image can be output from the XGA (extended graphics array).

2 is a block diagram showing a UPS expansion module 2 of a video recording apparatus according to the present invention.

In the UPS extension module 2, the current applied from the power supply unit is boosted by the step-up regulator 22 and is used to power the battery 23 composed of the lead- And the power of the main module 1 are supplied. In addition, an 8-bit microcomputer (MICOM) 24 is used to detect power failure and control battery power.

The system operation of the UPS expansion module 2 is roughly divided into two operations. First, the DVR functions as a surveillance device with 12Volt DC power supplied from an external power supply in a normal operation such as a non-power outage situation, and at the same time, the battery 23 installed therein always maintains full charge at all times. Next, in case of power outage, power is not supplied from external power supply when a power outage occurs. At this time, the battery installed in the DVR automatically supplies power to the DVR, so that all functions .

The microcomputer 24 constantly monitors the voltage at the power input terminal of the main module 1 and the voltage at the power supply terminal of the battery 23 for the detection of the blackout and the low voltage of the battery 23, The power of the battery 23 is applied (ON) to the main module 1 so that the continuous power supply is performed. Also, if the battery voltage falls below a predetermined voltage during an emergency operation after a power failure occurs, a low battery log is transmitted to normally terminate the power of the image recording apparatus. When the battery 23 is not in a power failure state, the power connection between the battery 23 and the main module 1 is turned off and the battery 23 is charged. The microcomputer 24 always checks the low voltage state of the battery 23 so that the battery 23 can be appropriately charged and the battery 23 uses a 12V 1.2AH lead storage battery.

Specifically, the small microcomputer 24 installed in the UPS expansion module 2 transmits to the UART (Universal Asynchronous Receiver Transmitter) communication port that a power failure event has occurred in the main processor 10, which is a DVR CPU, The processor 10 records the occurrence of a power failure event and the occurrence time of the corresponding event in the memory 18 in the DVR, and provides the power failure event information when the user requests it. At this time, the small microcomputer 24 installed in the UPS expansion module 2 continuously monitors whether the external power source unit 21 is powered on again (power failure recovery).

The small microcomputer 24 installed in the UPS expansion module 2 continuously checks the voltage of the battery 23 during a power failure to check whether the battery voltage is discharged below the voltage at which the DVR equipment can operate.

The miniature microcomputer 24 installed in the UPS expansion module 2 constantly checks the voltage of the battery 23 at the time of power failure so that when the threshold voltage of the battery 23 reaches a predetermined threshold voltage before descending to an appropriate voltage at which the DVR equipment can operate, The main processor 10 transmits a voltage alarm event to the main processor 10 via the UART communication. Upon receiving the voltage alarm event, the main processor 10 records the battery voltage notification event in the internal memory 13, After the state is created, UART communication is sent to the UPS expansion module (2) to prepare for power shutdown.

Upon receiving the power shutdown preparation event, the UPS expansion module 2 cuts off the voltage of the battery 23 to turn off the DVR and protect the battery voltage from being overdischarged. The microcomputer 24 installed in the UPS expansion module 2 continuously monitors whether the power is re-applied from the external power source unit 21 (recovery of power failure). When the power recovery is confirmed, the power source of the DVR is powered, Mode.

In addition, the power connection of each module can be connected to the SATA power port to implement the UPS function without developing a separate derivative product to implement the UPS function. It is also preferable that power supply of the UPS expansion module 2 is implemented so as to be commonly used not only for the power supply of the main module 1 but also for a camera.

4, the back panel of the video recording apparatus rear module 4 includes a camera input unit 11a that receives video data of the camera 11, an audio input unit 11b that receives audio data, A video output unit 13 composed of HD Spot and SD Spot for outputting video data, a monitor output unit 14 composed of HDMI and VGA ports and outputting video data, a network connection terminal A power supply unit 25 for supplying power to the video recording apparatus, a power switch 25, a fan 26 for emitting heat of the video recording apparatus, An external audio output terminal 27, and a SATA terminal 28 for connection to an external storage device.

5 shows an example of a lead storage battery used in the battery 23 of the present invention.

A battery is made by depositing two different electrodes (the higher electrode having the higher potential and the lower electrode being the cathode) in the electrolyte, and the chemical energy of the active material and electrolyte of each electrode is converted into electrical energy To an electric circuit in an external circuit connecting the positive electrode and the negative electrode.

In particular, the difference from a dry cell (primary cell) is that its action is reversible. In other words, in order to perform electrical work in each circuit, when the active material of the electrode undergoes a chemical change and then the electrical energy is applied from the outside, the changed active material of the electrode can be reduced to the original material. At this time, pulling out the electric energy from the battery is called discharging, and charging the electric energy to the battery is called charging. A battery capable of repeated charging and discharging is referred to as a capacitor.

Lead storage batteries or lead storage batteries are secondary batteries using lead and sulfuric acid. It is mainly used for automobile battery and it has larger capacity and voltage than other secondary batteries. The structure of a typical secondary battery is composed of a lead oxide used as an anode ((+) pole) and a lead used as a cathode ((-) pole) in a concentrated sulfuric acid. (The anode refers to the electrode and the anode refers to the reduction electrode.) Although the spherical lead accumulator was inadequately sealed, it had to be filled with concentrated sulfuric acid periodically. However, the present lead acid battery is completely sealed, There is no danger of.

FIG. 6 shows the chemical reaction of the filamentary storage battery. The filamentary battery repeats charging and discharging in the following reaction.

(Fully charged) Pb + PbO ₂ + 2H ₂ SO ₄ ↔ 2PbSO ₄ + 2H ₂ O (fully discharged)

First, the cathode, which is a negative electrode, reacts with concentrated sulfuric acid to release lead sulfate and two electrons.

Pb (s) + H ₂ SO ₄ (1) -> PbSO ₄ (s) + 2e ^- + 2H ⁺

When these electrons flow along the conductor and meet the anode, the following reaction occurs.

^{PbO2 (s) + 2e - +} H 2 SO 4 (l) → PbSO 4 (s) + 2OH -

This reaction results in a voltage of about 2 volts from one cell, which is much higher than other cells.

7 shows an example of an uninterruptible power supply (UPS), which is an example of a UPS being sold as a general merchandise.

Uninterruptible power supply means a device that supplies high quality stable AC power by overcoming a power failure that can occur in a commercial power supply. When using a general power supply or a standby power supply, the uninterruptible power supply device may be caused by voltage fluctuation, frequency fluctuation, momentary power failure, It is a device to prevent power failure and supply stable power at all times.

As the demand for computers increases, the number of systems requiring reliability, such as finance, broadcasting, and industry, has increased. The introduction of UPSs for parallel operation is spreading, and all systems are networked As a result, there is a growing need to manage UPS on the network. UPS manufacturers are also monitoring and controlling the UPS remotely as well as remotely diagnosing and managing them, thereby enhancing the product's high added value, reliability and cost reduction.

In general, uninterruptible power supply is very expensive and large in size, so it is difficult to apply it to general CCTV installation and it is difficult to be universalized. The video recording apparatus according to the present invention can expect the following effects.
